Post Slug Condition in Oxygen

This tutorial provides the steps to register a custom condition so element’s can be output based on the slug of the current post / page.

Step 1

Install and activate Code Snippets plugin.

Go to Snippets > Add New.

Title: Post Slug Condition

if ( function_exists( 'oxygen_vsb_register_condition' ) ) {
		
	global $oxy_condition_operators;

		oxygen_vsb_register_condition(
			// Condition Name
			'Post Slug',

			// Values: The array of pre-set values the user can choose from.
			// Set the custom key's value to true to allow users to input custom values.
			array( 
				'options'=>array(),
				'custom' => true
			),

			// Operators
			$oxy_condition_operators['string'],

			// Callback Function: Name of function that will be used to handle the condition
			'lit_slug_fallback',

			// Condition Category: Default ones are Archive, Author, Other, Post, User
			'Post'
		);

	}

/**
	 * Callback function to handle the condition.
	 * @param  mixed 	$value    	Input value - in this case, string 'slug'
	 * @param  string 	$operator 	Comparison operator selected by the user, either contains or does not contain
	 *
	 * @return boolean 				true or false.
	 */

function lit_slug_fallback( $value, $operator ) {

	$current_post_slug = get_post_field( 'post_name', get_post() );

	$value = (string) $value;

	$current_post_slug = strtolower($current_post_slug);
	$value = strtolower($value);

	if ($operator == "==") {
		if ($current_post_slug == $value) {
			return true;
		} else {
			return false;
		}
	} else if ($operator == "!=") {
		if ($current_post_slug != $value) {
			return true;
		}  else {
			return false;
		}
	} else if ($operator == 'contains') {
		if (strpos($current_post_slug, $value) !== false)  {
			return true;
		} else {
			return false;
		}
	}  else if ($operator == 'does not contain') {
		if (strpos($current_post_slug, $value) === false) {
			return  true;
		} else {
			return false;
		}
	}
}

Set the snippet to run everywhere. Save changes and activate.

The condition will be found under ‘Post’. If it needs to be used with a specific post type only, this can be added a seperate condition using the ‘AND’ condition type.
